I am working with MPU6050 and STM32f103VE as master. When I wake up the sensor and ask for information it returns 3 bytes of zeroes and the protocol stops working. I only send the communication Part of my code to be more specific:void I2C_interface(v...
I Wanted to generate the microsecond delay function, I have tried below functions but these are not working, It will be good if someone knows the delay function.static inline void delay_us( uint32_t micros){ micros *= (SystemCoreClock / 1000000) / ...
I know it sounds like a dumb question but I cannot connect anymore to my STM32H753I_EVAL2 (that I've been using extensively for months). I checked the driver in Windows Peripheral Manager. It is properly installed and it shows the same driver DLL as ...
In our system the I2S is set up with DMA in full duplex mode (circular, no fifo). That works, we get all the halffull interrupts.Now, ideally, what we want is that some user input will reset the dma buffer pointer.I found that in order to do that we ...
Hi,How to set alarm and read the alarm flag?I already write the RTC_ALRMAR = 0x85 to set alarm 5sec and mask sec. But the reading of ALRAF in RTC_ISR was not changed to 1 after it matched 5sec. Can U help me? I already set the RTC value with my homet...
when program started interrupt is called but its read only one character and repeatedly read same character.most time getting garbage value. RXNE Flag also set. my application is to handle data send by ATMEGA16 in while condition.program: voi...
Can't seem to find more information on programming PVD and External interrupt 16 in STM32F427 series. Please share the sample code if available.
Hi everyone,This is a fairly straight forward question. The STM32F301x4 and STM32F302x4 are listed on DigiKey as a non-stock item but are still present on the website when searched. I was unable to find any reference manual for these parts as well. A...
Hi,I am just going through manuals to understand power circuitry on STM32F4 Discovery board for using ADC for voltage sensing.Kindly help in understand difference between internal voltages (VDDA,VSSA,VDD, VREF+ etc) and other impact on power circuitr...
